The Acer with crystal eye webcam will also have a built-in microphone. The webcam is in the center at the top of the screen. The built-in microphone is typically half-way between the edge of the screen and the webcam. It is a little opening with a microphone logo beside it. You can test both audio input with the built-in microphone and the audio output with the built-in speakers by doing the following....
1. click start > Control Panel > Sounds and Audio Devices
2. in the Sounds and Audio Devices Properties click the Voice tab, then click the Test hardware button
3. in the Sound Hardware Test Wizard window click the Next button, if required, click unblock...
4. speak into microphone to do the Microphone Test. Recording meter will show movement if it works.
5. click Next button to do the Speaker Test. Microphone input is now output on the speakers.
6. click Next button when finished doing the readings and click Finish to close the wizard.

Have you looked into the settings inside windows at all? You can adjust the input levels and that might help.

Click Start/All Programs/Accessories/Sound Recorder. Click Start Recording and talk to your computer in a normal voice. When you finish click Stop Recording. Type in a file name and click save. Open the file and play it. If it works you have a built in mike, otherwise buy yourself an external, which I recommend anyway, because the built in mikes are generally not good enough for voice recognition or VOIP.

go to properties..you can either choose to work with build in mic or external.simply highlight input source and you are ready to go...
good luck

maybe the computer came with a cd for it that u have to install so the built in microphone work.
